Has anyone here added an extra fuel tank in the spare tire area? I'm thinking about moving the spare up to a mount on the rear bumper (if I can find one) and putting a spare fuel tank in its place. Has anyone tried this? I can't seem to find anyone who carries aftermarket fuel tanks that can be bolted up underneath the truck. Do the pickups have secondary tanks anymore? I haven't paid attention. I have a '97 Eddie Bauer. looks like there is plenty of room in there. It would be nice to double the range on this beast. Maybe I'll just fill the spare tire full of gas. And while I'm here, anyone have any ideas on the bumper mounted spare? Curt makes a front mounted hitch you can put a spare on, but I plan on putting a Bull Bar and winch up there soon. (don't anybody tell my wife please) I guess I'll just hang out over here in the corner now until someone notices me.
